Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building installation engineering, and particularly relates to an external wall thermal insulation structure, which can save energy and keep warm. Background Technique
[0002] Since the heat transfer of the external wall accounts for most of the heat loss of the building, low-energy buildings have put forward higher requirements for the energy-saving ability of the external wall. However, in the current construction process of external wall external thermal insulation, energy-saving thermal insulation boards often adopt a direct pasting installation method. Due to the diversity of the shape of the building external wall and the errors generated during construction operations such as the cutting of thermal insulation boards, there are gaps for air flow between the boards during the laying of thermal insulation boards. The air exchanges heat efficiently at the board joints, forming a thermal bridge on the external wall (the thermal insulation board can be a graphite polystyrene board, a polystyrene board or an extruded polystyrene board, etc.), resulting in an increase in the heat loss of the building in winter, an increase in the heating energy consumption of the building, and a decrease in the comfort of indoor personnel. Content of the Utility Model
[0003] The purpose of the utility model is to provide an external wall thermal insulation structure, which reduces the common thermal bridge effect and heat loss problems in the installation of external wall external thermal insulation, and saves energy and keeps warm.
[0004] The adopted technical solution is as follows:
[0005] The external wall thermal insulation structure includes a base wall, a mortar leveling layer and a thermal insulation board layer.
[0006] The thermal insulation board layer is fixed to the base wall through the mortar leveling layer. Its characteristics are:
[0007] The thermal insulation board layer includes multiple thermal insulation boards. Grooves are opened at the outer side of the joints of adjacent thermal insulation boards, and a thermal insulation filling layer is filled in the grooves.
[0008] The thermal insulation filling layer can be a polyurethane layer.
[0009] The thermal insulation board layer is a graphite polystyrene board layer, a polystyrene board layer or an extruded polystyrene board layer.
[0010] An anti-cracking protection layer is fixedly arranged on the outer side of the thermal insulation board layer.
[0011] A decorative layer is fixedly arranged on the outer side of the anti-cracking protection layer.
[0012] Its advantages are:
[0013] The utility model is applicable to the external wall external thermal insulation system. The gaps between the thermal insulation boards are filled with polyurethane, which saves energy and keeps warm, and reduces the thermal bridge effect at the joints of the external wall external thermal insulation materials.
